A student is given an antacid tablet that weighed 5.6832g. The tablet was crushed and 4.3628g of the antacid was added to 200 mL of stimulated stomach acid. This was allowed to react and then filtered. It was found that 25 mL of this partially neutralized stomach acid required 8.50 mL of NAOH solution to titrations it to a methyl red endpoint. It took 21.54 mL of this NAOH solution to neutralize 25 mL of the original stomach acid. a)How much of the stomach acid had been neutralized in the 25 mL sample which was titrations? (Show work) B) how much stomach acid was neutralized by the 4.3628 g sample used? (Show work) C)How much stomach acid would have been neutralized by the original 5.6832 g tablet? (Show work)

An unknown sample containing mixed alkal (NaOH NaHCO or Na,CO) was analyzed using the double flask method, A 250 mg sample was dissolved in 250 m CO3 free water. A 20.0 mL aliquot of this sample required 11.3 ml. of 0.009125 M HCl solution to reach the phenolphthalein end point. Another 29.0 ml aliquot of the sample was bitrated to the bromocresol green endpoint using 31.1 ml of the standard acid. How many millimoles of the components are there in the original solid sample) 0-928 mmol No. 0.0103 mmol NaOH 0078 m N.CO Cannot be determined 012 mol NaC0, 197 minol NaHCO 129 mmol NaOH, 097ml Najco
Twenty sodium salicylate tablets labeled 325 mg were dispersed in sufficient water to make 200.0 ml. A 15.0-ml aliquot of the filtrate was titrated to a bromophenol blue end point in the usual way by 29.11 ml of 0.1000 N hydrochloric acid. Calculate the amount of sodium salicylate in each tablet and, from that, the percentage of the labeled amount. Hint: Use the above formula.
Standard solution : 0.201 grams of acetylsalicylic acid was combined with 10 mL of 0.5 M NaOH, then transfered to a 100 mL flask and filled the rest of the way with water Then 0.500 mLs of the standard solution was transfered to a 10.00 mL flask and diluted to the 10 mL mark with 0.02 M of buffered iron chloride. This step was repeated using 0.400, 0.300, 0.200, 0.100 mLs of the standard solution Questions: A.) determine the concentration of the acetylsalicylic acid in the 100.00 mL volumetric flask containing the solution from which the standards were made. B.)determine the concentration of the acetylsalicylic acid in each of the 10.00 mL calibration solutions. I only need the work for 0.400 mLs C.)Make a scatter plot (on the computer again) of absorbance versus concentration for the calibration samples. On the plot, add a linear trendline, and display the equation and the R2 value on the chart. Take your time to label the axes
The Merck Index indicates that 10 mg of guanidine,CH5N3, may be administered for each kilogram of bodymass in the treatment of myasthenia gravis. The nitrogenin a 4-tablet sample that had a total mass of 7.50 g wasconverted to ammonia by a Kjeldahl digestion, followedby distillation into 100.0 mL of 0.1750 M HCl. Theanalysis was completed by titrating the excess acid with11.37 mL of 0.1080 M NaOH. How many of thesetablets represent a proper dose for a patient who weighs(a) 100 lb, (b) 150 lb, and (c) 275 lb?

Number of moles of NaOH = 0.005 moles Since the reaction between acetylsalicylic acid and NaOH is a 1:1 reaction, the number of moles of acetylsalicylic acid used in the reaction is also 0.005 moles. the concentration from analysis question 5: acetylsalicylic acid in the 100.00 mL volumetric flask is 0.050 M. From your plot, what is the value of εb? From the Beer- Lambert law For the aspirin sample, calculate the concentration of acetylsalicylic acid present using the value of εb that you found The concentration from analysis question 5 represents the concentration in the 10.00 mL sample that was prepared in the volumetric flask using an aliquot of the solution in the…
